Application filed April 29, I914. Serial No. 835,068.

1/ 0 all whom it may concern Be it known that I, GUSTAV M. LAGERGREN,

a citizen of the United States, residing inv the cityof New London, county of New London, and State of Connecticut, have invented certain new and useful Improvements in Submersible Boats; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which .it appertains'to make and use the same.

This invention relates to submersible boats and is directed .to the provisionof an improved mechanism for operating the hydroplanes or horizontal rudders of such vessels. Such hydroplanes should be capable of movement to an inoperative posit-ion parallel and close to the sides of the vessel or to an extended position at right angles to the sides of the vessel and when they are in the extended position, adjustment thereof to any desired angular position is necessary.

The primary object of the invention is to provide an improved operating mechanism whereby such hydroplanes or steering blades may be moved from a shipped position against the sides of the vessel to an extended position at right angles to the sides of the vessel and whereby a continued movement of the operating mechanism will turn the'blades on their longitudinal axes into.

any desired steering position near the horizontal but tipped slightly up at the aft edge for downward steering or down at the aft edge for upward steering, the mechanism'beiug so constructed that a reverse movement thereofwill bring the hydroplanes back to a vertical position and then cause them to assume their inoperative position against the sides of the vessel.

A further object of the invention is to provide means for limiting the travel of the hydroplanes on their vertical and horizontal axes.

A still further objectof the invention is to provide means for the purposes set forth. which shall be simple in construction and thoroughly reliable and. effective in operation. i

With the .above and other objects in view the invention consists in the. features of construction and. combinations of parts hereinafter described and claimed. I

In the accompanying drawings, Figure 1 is a plan view of a portion of the bow of a submarine boat, the superstructure being shown with its top removed and the hydroplanes being shown in their extended and horizontal position; Fig. 2 is a horizontal sectional view with the hydroplanes at right angles to the vessel Fig. 3 is asimilar view illustrating the mechanism when the hydroplanes are in their folded position; Fig. 4 is a vertical cross-sectional view showing the means for stopping the movement of the hydroplanes on their vertical axes. andthe roller for preventing play or movement of the hydroplanes when in their extended position; Fig. 5 is a longitudinal section through a portion of the hull and superstructure showing ;in elevation the hydro planes actuating mechanism and controlling connections; Fig. 6 is a sectional elevation showing the means for turning the hydroplanes on their horizontal axes.v and also the stop devices: Fig. 7 is a detail view of the inner end of one of the lrvdroplane shafts, and Fig. 8 is a cross-sectional view on the line 8-8 of Fig. 7.

The general arrangement of the hydroplanes with respect to the rest of the boat is shown in Figs. 1 and 5. The hydroplanes 1 and their actuating mechanism are supported in a casting 2. which is mounted on supporting beams 3. resting on the hull 4 of the "essel and extending lengthwise thereof.

' This casting interrupts the continuity of tl]( walls of the superstructure 5 as shown. so that'the casting is in fact built into the superstructure. and extends beyond the sides thereof a sufficient distance to permit the free movement of the planes on their vertical and-horizontal axes. The steering operation is effected by means of the steering shaft 6. which extends lengthwise of the superstructure. supported in bearings not shown. and should be continued to a convenient point within the vessel. .where it is connected with the steering wheel. This shaft 6 is connected through a unive rsal coupling'8 to a worm gear 9 which is journaled in bearings 10 in the casting, and engages with the toothed sectors 11. tors 11 are loosely mounted on pintles 12 having their hearings in boxes or journals 13 at the upper and lower ends of the casting 2, said pintles projecting from the easings or housings 14 in which the hydroplane shafts 15 are located and have their hearing, and forming the vertical axes 0n which said shafts are moved to their extended and their folded positions.

On the outer ends of the shafts 15 are prd vi'ded sockets to receive the inner ends of the hydroplanes, which may be secured'in place in any preferred manner. The inner ends of the housings 11 are formed with curved slots 17, in which fit lugs or pins 18, extending from the shafts 15. By this arrangement the play of the hydroplanes is limited from a vertical to a substantially horizontal position, and vice versa, the lugs or pins abutting against. the ends of the slotswhen the extreme positions have been reached and preventing further movement. On the inner ends of the shafts 15 are provided gear segments 19, which mesh with toothed racks 20, located on the under faces of the toothed sectors 11. so that when the latter are moved, the shafts 15 are caused to'turn on their horizontal axes to the extent permitted by the slots 17 in which the lugs 18 move. Extending laterally from the peripheral portions of gears 19 concentric with shafts 15, are curved flanges 21, the outer faces of which are adapted to engage a roller 22 mounted in bearings 23 projecting from the edges of walls or shelves 24 which are formed integrally with the casting 2, or secured thereto. bears against the outer faces of the flanges 21 when the hydroplanes have reached their extended position and begin their movement from a vertical to a horizontal position. This roller not only facilitates the partial rotation of the shafts 15, but also braces the hydroplanes in their extended position and prevents backward movement or chattering thereof.

To arrest the movement of the hydro planes after they have reached'their extended position. stops 25 are provided on the bottom of the casting 2. and these stops are engaged by projections 26. depending from the housings 11. Also stops 27 may be formed on gears 11 coacting with lugs 28 formed on the overlying member of frame 2.

''hen the hydroplanes are shipped, the upper ends of the flanges 21 bear against the under faces of the shelves 24. As the hydroplanes are moved to the extended position, the, flanges 21 pass from under walls 24 just as the stops 25 are reached and then turning of the shafts 15 1n bearings 14 1s possible.

These toothed sec-' This roller 22 the hydroplanes, the steering wheel is operated to turn the steering shaft 6 and thus revolve worm gear 9, and this worm gear meshing with the sectors 11 moves them on their vertical axes. The shafts 15 and the sectors 11 are locked together by reason of the fact that the racks 20 on sectors 11 are in mesh with the gear segments 19 on the shafts 15 and these gear segments 19 are prevented from rota-ting by the ends, of the flanges 21, which bear against the under faces of the shelves 2 1. \Vhen the flanges 21 pass beyond the shelves 24, the stops 25 for limiting the movement of the hydroplanes on their vertical axes are reached, and further movement is prevented. At this period of .the operation. the continued turning of the steering wheel causes the toothed sectors 11 to continue their turning movementand,-as the shafts 15 are now free to rotate on their axis, they are partially rotated through the gear segments 19 and the toothed racks 20, thus causing the hydroplanes to be turned on their longitudinal ,axes toward the horizontal position. .This movement may be continued until the hydroplanes have reached the desired steering position, which will be slightly short of the horizontal for upward steering and slightly beyond the horizontal fordownward steering. WVhen the hydroplanes reach the predetermined limiting position, the lugs or pins 18 engage the ends of the slots 17. and hence the further turning of the shafts 15 is prevented. During the period of .use of the hydroplanes the steering angle may be altered at will by turning the steering shaft 6, as will be understood.

"In the operation of folding the hydroplans, a reverse movementof the steering Wheel causes thesh'afts 15 to turn on their at this time cleared theroller 22, and further turning of sectors 11 causes the segments 19 to be moved bodily, carrying the flanges 21 under shelves 24. This locks shafts 15 against further turning movement tliroggh their gear connection with the sectors 11 and "the hydroplanes assume their position against the sides of the Boat.

It will seen that by the mechanism described the hydroplanes maybe extended from av position substantially parallel with the sides of the boat to a position at right angles thereto, and that by the'continued action ofthe mechanism, the hydroplanes may be caused to assume any desired degree of" angularity. Furthermore, it will be noted that a, single operating mechanism performs the two-fold function of shipping or extending the planescand adjusting the angular position thereof as desired. This mechanism is such that the hydroplanes cannot be moved back against the sides of the boat except in such angular position as will cant": them to lie flat against the sides of the boat. It will also be noted that the hydroplanes are locked in any position to which they are moved for the reason that while the worm gear may turn the. sectors, the reverse operation of the sectors upon the worm gear is .impossible.
